what do farmers cultivate plants of legume family?
Answers
Answer:
The bacterium is Rhizobium is found in the root nodules of leguminous plants such as peas. It lives in symbiotic association withplants and fixes the atmospheric nitrogen in leguminous plants. This increases the fertility of the soil. Hence, farmers cultivate plants belonging to the legume family.
Leguminous plants are cultivated to restore the nitrogen levels in the soil.
Explanation:
Leguminous plants are known for the nodule formation on their roots. Nodule formation on the roots of the plants belonging to the family Fabaceae (Leguminosae) because of the bacterial infection caused by bacteria Rhizobium. Leguminous plants are so important in agriculture because of the symbiotic relation between the microbe Rhizobium and the plant. Rhizobium is a nitrogen fixating bacteria and nitrogen is an essential component for plant growth. Hence the bacteria derives nutrition from the plant for its survival and in turn provides the plant with nitrogen, existing in a symbiotic relationship they also help fulfill the atmospheric nitrogen cycle.
Crop rotation is a common practice among farmers to ensure the soil does not loose its fertility and the macro and micro nutrients in the soil are balanced.
